For all us male "MEMBERS" how apt that word is!with a touch of ED, i had the same problem, a friend suggested "cock rings" I found some on Amazon of all places, the ones I have are three simple silicone maybe rings, you get three it is recommended to put one around your testies one or two on your shaft, they are quite comfy, my lady says they make my equipment look sexy, they certainly help me get a very hard erection.
The first time we used them it was super great sex, a day or so later we were both sore, maybe friction burns Ha. we think it maybe the material they are made from that affected us, we now put Vaseline on the rings first, no more problems now, sex life is much better now, simple cure/help.
I also use them for self satisfaction too, great stuff.
They are not expensive either.
Hope this helps some of you blokes out there.
I will be 69 soon.
Happy new year.
